If this node isn't O_RDWR, only return the appropiate memobj.

Open exec's realnode read-only for now, since we know it doesn't matter and
having gratuitously writable nodes around prevents us from starting up or
going read-only.

|
|
Open the new translator's realnode read-only for now, since we know it
doesn't matter and gratuitously writable nodes prevent us from starting up
or going read-only. The fsys_startup interface should change very soon and
make this irrelevant anyway.
